Everything is cause and effect. Except, of course, there is no reason to say such a thing. - me,1989 Does anyone have source to the parallel port device? I have a parallel attachment which does robot control and I want efficiency. So I would like to make a patch to the driver. I THINK I need every piece of code and Lattice linking instructions. Do I? Please don't tell me that I don't want to customize the device, I have special reasons... Can anyone help? (roger rabbit mode ON) Puulleeeaaaze??? thanks! Don White Box 271177 Concord, CA. 94527-1177

You won't need any change to the parallel.device just to get control over the parallel port. The hardware (i.e., one of the CIAs) is arbitrated via the misc.resource, you can easily grab the port and noone can interfere. You can get the interrupt line (ACK line from your printer) and even get the serial shift register via the ciab.resource. I've connected a GAL programmer to my printer port and use this method to access all control lines. Michael van Elst E-mail: UUCP: ...uunet!unido!fauern!immd4!mlelstv
